Vulnerability Title
Invalid pointer dereference in d2i_PKCS7 functions
Source: NVD (National Vulnerability Database)
Vulnerability Description
An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL does not call this function however third party applications might call these functions on untrusted data.
